Has anybody used Zillow Premier Agent? Are the leads worth it?

[Hemanth Grandhige]

I quit my job a year ago and spent the last year flipping and building my rental portfolio.  I can't say I'm upset with the way things have gone but I need a steady income to keep everything moving forward.  I got my real estate license and just parked it as an assistant under my mentor. (She is an agent with ReMax.)  I'm thinking of pulling it out, dusting it off, and getting some listings.  

I have been contacted multiple times by Zillow to sign up as a premier agent.  The cost isn't terrible, a couple hundred a month at the most.  They claim the leads increase 44x that of just listing yourself on their website.  

Does anybody have any experience using Zillow Premier agent?  If so I'd appreciate any insight you can provide regarding getting the most from the service.

Thanks,
